no ride on helicopters, only to load with gold like the frontinos have, in regard to what to touch? you don't have to worry cuze they go with you the geologist or an assistan or an expert, but when you get to see and touch the veins man, that is something that you heart going nuts.
the explain you what is what and how the follow the veins and when they screw up too..lol..lo for real.
All I have to say is I'm here to give my personal opinion, and you don't have to follow my advice, please do your own DD before you invest. And don't blame others for your bad choices".
